Testing and Demonstration of MODIS Data Transfers

Testing and Demonstration of MODIS Data Transfers

Natural Resource Area (Earth Monitoring WG and Agriculture WG) Report Chris Elvidge, NOAA-NGDC [email protected] January 26, 2006 On-Going Earth Observation Data Transfers Via APAN DMSP: ~500 MB per day from NGDC to

MAFF. ASTER: 60 GB per day from NASA-GSFC to JAXA (ERSDAC). ASTER: 70 GB per day from ERSDAC to USGS. TRMM: from NASA-GSFC to JAXA. AVHRR & MODIS: 3-5 GB per day from AIT to MAFF. Near Term Planned/Potential Earth

Observation Data Transfers Via APAN AMSR-E: 1.4 GB per day from NASAGSFC to JAXA. 2006 start. ALOS: Transfers from JAXA to regional nodes. 2006 start. XSAR: 500 GB per day transfers from ESA to JAXA. 2006 start? Longer Term Planned/Potential Earth Observation Data Transfers Via APAN NPP data transfer from NOAA (up to 2 TB per day). Start in 2009? Portions to

multiple destinations in Asia Pacific. GCOM-W data transfers from JAXA. Start in 2010? GCOM-C data transfers from JAXA. Start in 2011? Others TBD. NASA-MODIS Data Transfer Test NGDC placed one days worth of raw MODIS data (70 GB) at our ftp site. MAFF tested the transfer rate by ftp. NGDC and MAFF worked together to improve the transfer rate.

Advice was received from TransPac and the APAN NOC. NGDC Data Route NCAR National Center for Atmospheric Research FRGP Front Range Gigapop

Abilene Trans Pac-2 APAN MAFF CC Results Initial tests yielded a transfer rate of 420 KB per

second = 35 GB per day. NGDC moved the data to dedicated ftp server. NGDC and MAFF tune the tcp/ip stack using the same settings. Retesting yielded 5 MB per second with single stream more than 400 GB per day. Parallel streams yielded 10 MB per second more than 800 GB per day.
